    • PROBLEM TO BE SOLVED: To provide a bristle configuration providing enhanced cleaning of teeth. SOLUTION: The bristle pattern includes large tufts having a greater cross-sectional area than standard toothbrush bristle tufts. The large tufts are contoured so that the top ends of the bristles comprising the large tufts are not all at the same height. More than one raised section is provided, the raised sections being spatially isolated from one another to function independently of one another. Preferably, at least one of the raised sections has a sufficient brushing surface area with bristles extending a sufficient height above surrounding bristles such that that raised section can reach into and clean interdental tooth surfaces, preferably while the remaining bristles in the large tuft clean other tooth surfaces. Another aspect of the invention relates to a zig-zag or sawtooth bristle profile, wherein each tuft making up the profile has its own unique substantially conical or frustoconical profile. In one embodiment, the height of conical or frustoconical bristle tufts increases from the sides of the head towards the midline of the head. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供刷牙配置,提供增强的牙齿清洁。

      解决方案:刷毛图案包括具有比标准牙刷刷毛簇更大的横截面积的大簇。 大的毛束具有轮廓,使得包括大簇的刷毛的顶端并不全部处于相同的高度。 提供了多个凸起部分,凸起部分在空间上彼此隔离以彼此独立地起作用。 优选地,凸起部分中的至少一个具有足够的刷牙表面区域,刷毛在周围的刷毛上方延伸足够的高度,使得该凸起部分可以进入并清洁牙齿间表面,优选地在大簇的剩余刷毛清洁其他牙齿 表面。 本发明的另一方面涉及锯齿形或锯齿状刷毛轮廓,其中构成轮廓的每个簇具有其独特的基本上圆锥形或截头圆锥形轮廓。 在一个实施例中,锥形或截头圆锥形刷毛簇的高度从头部的侧面朝向头部的中线增加。 版权所有(C)2011,JPO&INPIT
